Specification of Letters Patent.

Patented June 26, 1906.

ipplioation filed December 28,1904 Serial No. 238,615.

To all whom, it may concern:

Be it known that we, ISAAC B. LOWRY and FRANK L. ARTnRs, citizens of theUnited States, residing at Montpelier, in the county of Blackford, Stateof Indiana, have invented certain new and useful Improvements inWire-Stretchers; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to wire-grips, and has for its object to providea cheap and simple construction which will comprise but few parts, whichwill tightly grip a wire with which it is engaged, and which may beeasily and quickly engaged and disengaged. Other objects and advanta esof the invention will be understood from the following description.

In the drawin s formin a portion of this specification, an in whic likenumerals of reference indicate similar parts in both views, Figure 1 isaperspectiveview of awiregrip embodying the present invention andengaged with a wire. Fig. 2 is a longitudinal section through the guidesand gripping-j aws.

Referring now to the drawings, the present wire-grip comprises a plateor body portion 5, one face of which is flat, and from this flat face,at the upper and lower edges thereof, project ideWaysG and 7, whichextend first outwar 1y at right an les to the face of the plate and thentoward each other, the outwardly-proj ecting portions having their innerfaces converged, while those portions extending toward eachother are ina common plane parallel with the face of the plate 5, from which theguides project.

Between each of the guides and the face of the plate 5- is slidablymounted a grippingjaw, (shown at 8 and 9.) Enga ed in the slots 12 and13 are springs 16, whic have one of their ends engaged with one of theend walls of the slot and have their other ends engaged with the pins 14and 15, the said sprinlgls serving to retract the said jaws after a sligt forward movement of the grip, these grippingjaws being tapered tocorrespond to the convergent faces of the guides, so that when the jawsare moved in the direction of one end of the plate 5 they will be forcedtoward each other to grip the wire 10 therebetween and when moved -inthe opposite direction they may be separated' The guides 6 and 7 areslotted, as shown at 12 and 13, the slots conver ing to correspond tothe convergent faces of t e guides, and in these slots lie pins orscrews 14 and 15 respectively, which are engaged with the jaws andprevent the latter from moving longitudinally from beneath the guides.The ides are located at one end portion of the plate 5, and through theopposite end of the plate is a perforation 14, in which is engaged aring 15 for attachment of any suitable means for moving the grip afterit is engaged with the wire to stretch the latter.

The mutually-adjacent faces of the gripping-jaws are provided withteeth, as ilus- ,trated, to facilitate their gripping action.

What is claimed is 1. A wire-grip comprising a plate rovided with slots,jaws mounted u on said p ate, pins carried by said jaws an engagedthrough said slots, and springs mounted in said slots in engagement withsaid pins for normally holding the said jaws out of engagement with eachother.

2. A wireip comprising a plate'having recessed gui es formed thereon,one of the walls of each of said guides being provided with a lonitudinal slot, the said slots being converged ongitudinally toward eachother and lying in the same plane as the adjacent wall of its respectiverecess, jaws mounted in said recessed guides, pins carried by said jawsand en aged through said slots, and springs engaged in said slots and inengagement with said pins for normally holding said jaws outofengagement with each other.

In testimony whereof we aflix our signatures in presence of twowitnesses.
